I'll admit that it sounds awesome, at the same time I loath mods adding weight to the currency. I don't understand why this mod adds it, it's about jewelry what does it have to with money weight?
The author has stated on the mods description page and in this thread a weightless coins version is available. personally I prefer weight to my coins. You deal with it by using the "Exchange Currency" mod as the description explains. These notes given to you are very lore friendly and very close to how the banking system worked in the medieval and early renaissance.
Future mods can exploring the excitement of "Immersive Double Entry Book Keeping", HDT titteh mods to display the health of your fractional reserve banking. I personally can not wait for Gamwich's rustic fiat currencies.
Joking aside all respect to to Forteverrum, great mod now part of my standard build.
